Subject: [PATCH 27/27] ALSA: hda/cs8409: Unmute/Mute codec when stream starts/stops
Date: Mon, 26 Jul 2021 18:46:40 +0100	[thread overview]
Message-ID: <20210726174640.6390-28-vitalyr@opensource.cirrus.com> (raw)
In-Reply-To: <20210726174640.6390-1-vitalyr@opensource.cirrus.com>

From: Stefan Binding <sbinding@opensource.cirrus.com>

Codec is muted on init, and then unmuted when the stream starts.
